Abstract

Abstrak Jurnal ini mendiskusikan analisis coverage dan handover jaringan LTE untuk kereta cepat Jakarta-Surabaya. Penelitian dilakukan dengan mengadopsi teknologi LTE yang dibangun koridor rel kereta untuk mendukung kecepatan 160 km/jam pada daerah tinjauan track Jakarta-Cirebon. Perhitungan radius cover dan jarak antar site menggunakan frekuensi 900 MHz dengan model propagasi Okumura-Hatta. Langkah sebelumnya adalah melakukan kalkukasi path loss uplink dan downlink dengan nilai link budget. Besar radius adalah 1,86 km berdasarkan model propagasi yang digunakan. Dengan wide area 219 km2 diperoleh jumlah site uniform sebanyak 39. Kondisi rel yang berbeda-beda mempengaruhi jarak antara rel dengan site existing yang digunakan. Pada kasus tersebut perlu dilakukan validasi dengan menggunakan radius site existing sesungguhnya. Perhitungan validasi membutuhkan jarak overlapped saat kereta melakukan handover. Hasil simulasi X2 handover menggunakan NS3 diperoleh nilai rata-rata delay transmission data sebesar 15,14 ms. Dari nilai tersebut diperoleh jarak overlapped sebesar 600m. Dengan menggunakan teori Pythagoras diperoleh jumlah site sebanyak 47. Setelah melakukan simulasi menggunakan software Atoll, analisis coverage by signal level atau RSRP dan SINR telah memenuhi standar yang digunakan. Kata kunci : Kereta Cepat 160 km/jam, LTE, Coverage, Handover. Abstract This journal discusses the analysis of the coverage and submission of the LTE network for the JakartaSurabaya high speed train.

The radius calculation includes and the distance between sites using the 900 MHz frequency with the Okumura-Hatta propagation model. The previous step is calculate the path loss uplink and downlink with the value of the link budget. Value of radius cover is 1.86 km based on the propagation model used. With wide area of 219 km2, there were 39 uniform sites. Different rail conditions differ between rails and existing sites used. In this case, validation is needed by using the existing site radius. Validation calculations require overlapping distances when delivering trains. The X2 handover simulation results using NS3 obtained an average value of data transmission delay of 15.14 ms. From this value overlapping distance of 600m is obtained. By using Pythagoras theory, there are 47 sites. After calculating using software Atoll, analysis of coverage with signal level or RSRP and SINR has obtained the standard used. Keywords: High Speed Railway 160 km/jam, LTE, Coverage, Handover

Abstract

Abstrak Transportasi kereta merupakan salah satu transportasi pilihan antar kota yang pengembangannya terus dilakukan. Perancangan jaringan wifi di kereta merupakan salah satu bagian dari pengembangan layanan kereta cepat. Namun, dalam sistem komuniaksi WLAN terdapat masalah yang dapat mengurangi kualitas performansi jaringan internet, salah satunya adalah masalah hidden node. Masalah hidden node menyebabkan terjadinya collision yang turut mempengaruhi performansi jaringan menjadi menurun. IEEE 802.11n memanfaatkan mekanisme RTS/CTS yang digunakan untuk meminimalisir collision pada jaringan akibat masalah hidden node. Pada Tugas Akhir ini dilakukan analisis pengaruh hidden node pada QoS layanan IEEE 802.11n WLAN di gerbong kereta cepat. Pengujian yang dilakukan berupa simulasi menggunakan simulator NS3.26. Pada proses simulasi digunakan 4 skenario yaitu hidden node pada saat penumpang melakukan layanan VoIP, data, video streaming, dan mixed layanan. Parameter-parameter yang dianalisis pada Tugas Akhir ini adalah throughput, delay danPDR dengan menggunakan mekanisme RTS/CTS. Pengujian hidden node yang dilakukan terhadap payload size layanan VoIP, data, dan video streaming dengan nilai minimum dari standar ITU-T berpengaruh pada hasil throughput. Berdasarkan hasil pengujian hidden node layanan VoIP, data (web browsing), video streaming, dan mixed layanan menunjukkan komposisi pengujian 1 (48N + 2HN) menghasilkan throughput, delay, dan PDR yang tergolong bagus karena throughput yang dihasilkan tinggi, delay yang diperoleh ≤ 150 ms dan PDR untuk kondisi RTS/CTS enable 100%. Sedangkan, untuk komposisi pengujian 2, 3, dan 4 menghasilkan performansi jaringan yang buruk karena tidak sesuai dengan standar ITU-T G.1010. Penggunaan mekanisme RTS/CTS enable untuk pengujian hidden node dapat meningkatkan performansi jaringan. Namun, penggunaan mekanisme RTS/CTS enable pada pengujian dengan jumlah 4, 8, dan 12 hidden node tidak efektif untuk meminimalisir collision yang terjadi karena permintaan transmisi pada jaringan menjadi semakin tinggi. Kata kunci : IEEE 802.11, Hidden Node, Access Point, RTS/CTS, NS3 Abstract Train transportation is one of the inter-city transportation options for which development continues. The design of a wifi network on a train is one part of developing a high speed train service. However, in the WLAN communication system there are problems that can reduce the quality of internet network performance, one of which is the hidden node problem. Hidden node problems cause collisions that also affect network performance to decrease. IEEE 802.11n utilizes the RTS/CTS mechanism used to minimize collisions on the network due to hidden node problems. In this final project, a hidden node analysis is performed on IEEE 802.11n WLAN in a fast train car. Tests carried out in the form of simulations using the NS3.26 simulator. In the simulation process, four scenarios are used, namely hidden nodes when passengers make VoIP services, data, video streaming, and mixed services. The parameters analyzed in this Final Project are throughput, delay and PDR using the RTS/CTS. Hidden node testing performed on the payload size of VoIP services, data, and video streaming with a minimum value of the ITU-T standard affects the results of throughput. Based on the hidden node test results of VoIP services, data (web browsing), video streaming, and mixed services show the composition of testing 1 (48N + 2HN) results in throughput, delay, and PDR that are relatively good because the resulting high throughput, the delay obtained is ≤ 150 ms and PDR for RTS/CTS conditions enable 100%. Meanwhile, the composition of tests 2, 3, and 4 results in poor network performance because it does not comply with ITU-T G.1010 standards. The use of the RTS/CTS mechanism enables hidden node testing to improve network performance. However, the use of the RTS/CTS mechanism allows the testing of the number of 4, 8, and 12 hidden nodes is not effective to minimize collisions that occur because of the higher transmission demand on the network Keywords : IEEE 802.11, Hidden Node, Access Point, RTS/CTS, NS3

Abstrak Menurut Badan Pusat Statistik (BPS) penggunaan kereta untuk perjalanan jauh menjadi pilihan utama untuk masyarakat karena biaya yang murah dan tepat waktu. Indonesia akan membangun sarana transportasi kereta cepat pada rute Jakarta – Surabaya dengan kecepatan 140 km/jam pada frekuensi 900 MHz. Namun, sisi negatif ketika berada di dalam kereta cepat, delay yang tinggi menyebabkan packet loss yang sangat besar. Demi menunjang kenyamanan penumpang selama melakukan komunikasi dalam perjalanan dilakukan penelitian agar terpenuhinya Quality of Service (QoS) pada kereta cepat dengan delay maksimal ≤ 40 ms. Metode yang digunakan yaitu coverage dan capacity planning menggunakan network dimensioning dan perhitungan jarak maksimum coverage untuk mengakumulasi jumlah site serta kapasitas tiap site yang diperlukan dan melakukan simulasi. Untuk perhitungan delay total menggunakan simulator delay. Simulasi jaringan microcell LTE dengan memperhitungkan letak eNodeB existing dan RRU extend yang dikhususkan untuk jalur kereta cepat dengan memperhatikan delay, throughput, SINR, RSRP dan overlapping Berdasarkan simulasi dan perhitungan diperoleh delay total sistem yaitu sebesar 38,6287 ms dan delay handover 20 ms. Nilai overlapping 1483 m dengan persentase coverage total area yang didapat yaitu 37,07%. Perancangan dengan adanya eNodeB existing menghasilkan RSRP -62,88 dBm, nilai SINR 8,96 dan jumlah site 37. Perancangan yang tidak memakai eNodeB existing memiliki hasil RSRP -64,81 dBm, SINR sebesar 8,74 dB dan jumlah site 38. Perancangan ini dikatakan layak karena memenuhi persyaratan LTE kereta cepat dimana delay total ≤ 40 ms dan kualitas jaringan memenuhi standar KPI Telkomsel. Kata Kunci: Delay, Handover, Overlapping, LTE, Kereta Cepat Abstract As stated by Badan Pusat Statistik (BPS), long distance travel by train become a first choice for the community because of the safety, low cost and right on time schedule. Indonesia will build high speed train facilities on the Jakarta - Surabaya route with speed 140 km/h at 900 MHz frequency. However, there is a disadvantage when on a high speed train, high latency lead to huge packet loss. In order to provide comfort for passenger during communication, thus a research is conducted on high speed train with maximum allowed delay ≤ 40 ms. Method that used during the research included the design of coverage areas and capacity planning using network dimensioning, which is a method for accumulating the number of sites and the capacity of each site needed. Performing simulation and calculating the total delay using a delay simulator. Simulation network of the LTE communication by taking coordinate existing eNodeB and RRU extend which are specifically for high speed train without neglecting to delay, throughput, SINR, RSRP and overlapping. Based on the simulation and calculation, the total system delay is 38.6287 ms and the handover delay is 20 ms. The value of overlapping is 1483 m with the percentage of total coverage area obtained is 37.07%. Network design that used existing RRU produced RSRP -62.88 dBm, SINR 8.96 and amount of sites are 37. Design that did not use the existing RRU has result RSRP -63.43 dBm, SINR values of 8.74 dB and make 38 sites. This design is feasible, because it meets the requirements of LTE high speed train where total delay ≤ 40 ms and network quality meet requirements Telkomsel KPI Keywords: Delay, Handover, Overlapping, LTE, High Speed Train

Abstract

Abstrak Kereta merupakan transportasi yang paling banyak digunakan untuk proses mobilisasi pekerja dari satu kota ke kota lainnya. Hal ini disebabkan laju kereta yang cepat sehingga waktu perjalanan menjadi lebih singkat. Efisiensi waktu selama perjalanan sangat dibutuhkan agar tetap produktif, khususnya bagi pekerja yang membutuhkan layanan internet. Pengadaan layanan internet dikereta perlu mempertimbangkan faktor reliabilitas baik dari aspek fisik maupun jaringan. Penelitian ini melakukan analisis terhadap reliabilitas access point dari aspek fisik dan jaringan. Analisis aspek fisik dilakukan berdasarkan kriteria yang ditetapkan oleh IEC 60077, sedangkan analisis pada aspek jaringan dilakukan berdasarkan nilai QoS yang dimiliki setiap access point. Skenario pengujian QoS dilakukan dengan meletekan access point ditengah gerbong kereta, dengan jumlah user 20, 30, 40, dan 52. Simulasi QoS dilakukan menggunakan Network Simulator 3.26 dengan memasukkan parameter tambahan berupa redaman sebesar 17 dB sebagai akibat yang ditimbulkan dari material pada gerbong kereta. Berdasarkan dua aspek tersebut, dapat diketahui bahwa access point terbaik jika ditinjau dari faktor nilai stres dan reliabilitas yaitu Huawei AP9131DN dengan nilai stres sebesar 125 dan reliabilitas sebesar 99.99921875%. apabila ditinjau dari faktor QoS, access point terbaik yaitu Teldat APR222n dengan nilai throughput sebesar 43.8059275 kbps, nilai delay sebesar 74.41269 ms, dan nilai jitter sebesar 7.27849 ns. Kata kunci : Reliabilitas, Stres, Access Point, Delay, Jitter, Throughput, Packet Loss Abstract Train is the most widely used transportation for the process of mobilizing workers from one city to another. This becomes even shorter. Time efficiency during the trip is needed so that it remains productive, especially for workers who need internet service. The procurement of internet services must consider the reliability factors from physical and network aspects. This research analyzes the reliability of access points from physical and network aspects. Analysis of physical aspects is carried out based on the criteria determined by IEC 60077, while analysis on the aspect of the network is carried out based on the QoS values required for each access point. The QoS testing scenario is done by erupting the access point in the middle of the train car, with a number of users 20, 30, 40, and 52. QoS simulations are carried out using Network Simulator 3.26 using parameters adding attenuation of 17 dB as a result of material on the train cars. Based on these two aspects, the best access point can be known if viewed from the stress and reliability value factors, namely Huawei AP9131DN with a stress value of 125 and reliability of 99.99921875%. It is estimated that in terms of the QoS factor, the best access point is Teldat APR222n with a throughput value of 43.8059275 kbps, a delay value of 74.41269 ms, and a jitter value of 7.27849 ns .

Abstract

Abstrak BPS Indonesia menyatakan pertumbuhan transportasi darat tertinggi wilayah pulau Jawa 2012-2016 adalah kereta api. PT Kereta Api Indonesia belum menyediakan layanan Internet di dalam kereta. Penelitian ini merancang jaringan Wi-Fi pada kereta cepat Jakarta-Surabaya menggunakan standar IEEE 802.11n. Pada jaringan tersebut terdapat server yang berfungsi menampung trafik user, serta menghubungkan jaringan internal (di dalam kereta) dan jaringan eksternal (di luar kereta). Pada jaringan server-gateway diperlukan scheduling untuk mengatur lalu lintas trafik user. Simulasi jaringan dilakukan menggunakan software NS-3. Parameter QoS yang digunakan adalah throughput, delay, dan packet loss, untuk layanan video streaming. Pengujian jaringan internal dilakukan bertahap 1-5 gerbong penumpang, menggunakan scheduling 10 ms, 100 ms, 250 ms, dan 500 ms. Pengujian jaringan eksternal dilakukan dengan membandingkan data simulasi dengan perhitungan menggunakan metode capacity planning. Pengujian 1 gerbong penumpang memperoleh throughput rata-rata user 0,426 Mbps, mendekati hasil perhitungan bandwidth yaitu 0,487 Mbps. Semakin banyak jumlah user maka throughput jaringan akan berkurang, dan semakin lama scheduling yang digunakan, delay-nya akan semakin tinggi. Pengujian scheduling 100 ms memiliki throughput yang relatif lebih stabil dan packet loss yang lelih rendah dibandingkan scheduling 10 ms, tetapi memiliki delay yang lebih tinggi. Pada simulasi jaringan eksternal kondisi terpadat, throughput pada sisi downlink 34,24036 Mbps, mendekati hasil perhitungan yaitu 36,39212 Mbps, kemudian delay yang diperoleh memenuhi standar yang digunakan yaitu 40 ms. Kata kunci: Wi-Fi, server, scheduling, kereta cepat Abstract BPS Indonesia states that the highest growth of land transportation in the Java region 2012-2016 is trains. PT Kereta Api Indonesia has not provided Internet services on the train. This Final Project designed a Wi-Fi network on the Jakarta-Surabaya fast train using the IEEE 802.11n standard. On the network there is a server that functions to accommodate user traffic, and connects internal networks (on the train) and external networks (outside the train). In the network servers, scheduling is needed to regulate user traffic. Network simulation is done using NS-3 software. The QoS parameters used are throughput, delay, and packet loss, for video streaming services. Internal network testing is done in phases of 1-5 carriage, using scheduling 10 ms, 100 ms, 250 ms, and 500 ms. External network testing is done by comparing simulation data with calculations using the capacity planning method. Testing of 1 carriage has a user average throughput of 0.426 Mbps, approaching the result of bandwidth calculation which is 0.487 Mbps. The more number of users, the network throughput will decrease, and the longer the scheduling is used, the delay will be higher. Testing scheduling 100 ms has relatively more stable throughput and low packet loss compared to scheduling 10 ms, but has a higher delay. In the simulation of the worst case on external network, the throughput on the downlink side is 34.24036 Mbps, meets the calculation result of 36.39212 Mbps, then the delay obtained meets the standard used which is 40 ms.

Abstract

This paper discusses the water management conducted by Telkom University, including the fundamental considerations to be taken into account, the implementing organization, the design methods for rainwater systems, and practical experiences in constructing Rainwater Harvesting systems. The management is aware of the conditions and situations related to clean water users, estimates of clean water requirements, potential water sources, and the campus environmental situation. Based on various studies and supported by rainfall data from the Meteorology, Climatology, and Geophysics Agency, a simple calculation was used to derive the design of the Rainwater Harvesting system, which was subsequently implemented. There are several lessons learned from this implementation, including the need for improvements in the foundation structure of soak pits, recommending the construction of ground tanks during the dry season, and the flexibility of ground tank size depending on the availability of funds The abstract should state briefly the purpose of the research, the principal results and major conclusions.
